The next thing to do is adjust the temperatures. You have been given incorrect information on that, probably by a pet store or a less-than-reputable website. Chameleons are adaptable to temperature extremes in their wild habitat, but there they can move around to find warmer or cooler spots. In a cage they have no choice. After months of being too cold, illness often develops. The coldest part of the cage should be 82.5*F. There should be a warm basking area that is kept at 89*F to 113*F. That sounds hot to us, but to a chameleon, it is just right. at night the temperature can be allowed to drop to 72*F to 79*F. Use a good digital probe thermometer to measure the temperature. You can adjust the temperature by raising or lowering the fixture or by changing the bulb to one with higher or lower wattage. If you have to lower the fixture, don't put it so low that your chameleon can touch it and be burned. I suggest that you read the information on this site for more advice on care:
My first suspicion was that Pascal is suffering from Metabolic Bone Disease (MBD). There is no way to be certain based only on an online description. You have done the right things to prevent that by having a UVB light and providing calcium. However, what pet stores don't tell you is that UVB bulbs with a 5.0 output are only good for 3 months. The bulbs put out both visible light and UVB light, which the human eye cannot see. After about 3 months, almost no UVB rays are emitted, but visible light continues for years. So, if your bulb is moire than 3 months old, Pascal could have MBD even though you've done everything to prevent that.
Chameleons are one of the most delicate of reptiles, and are more difficult to keep in captivity than most species. To complicate that, pet owners trust pet store personnel to give them good information on care, and that doesn't often happen. As a result, many chameleons die young. And, once they become weak or ill, they almost never recover without veterinary intervention. I recommend that you make an appointment. This link will take you to a directory of reptile vets:
In summary, I would begin Pedialyte soaks right away, adjust the temperature, and get a new UVB light if yours is over 3 months old. Also give strong consideration to a vet visit. If you have more questions, just let me know. I can tell you care very much for Pascal. I hope he will quickly return to good health.
